Improvement in water-wheels



UNITED STATES PATENT OFFICE.

SAMUEL DIEHL, OF MENALLEN, PENNSYLVANIA.

IMPROVEMENT IN WATER-WH EELS.

' Spccication forming part of Letters Patent No. 2,606, dated May 4,1842.

To @ZZ whom t may concern,.-

Be it known that I, SAMUEL DIEHL, ofMenallen township,Adams county,State of Pennsylvania, have inventeda new and useful Improvement in theHorizontal Percussion and Reaction Water-Wheel for Propelling Machinery,which is described as follows, reference being had to the annexeddrawings of the same, making part of this specification, of which-Figure l is a horizontal section through the center of the wheel,chutes, and penstock, showing ltheforms of these parts. Fig. 2represents aside elevation of the wheel, showing the form andarrangement of the buckets. Fig. 3 is a perspective viewof one of thebuckets detached,'showing the iianges and apertures in the same forscrews by which they are secured to the core of the Wheel. Figt is asection showing several straight buckets. Fig. 5 represents the form ofone of the blocks arranged behind the buckets.

This water-wheel generally is made like other wheels in use, theimprovement being in the form of the buckets A and in the arrangement ofcertain convex blocks B behind the buckets, for the purpose hereinafterstated, and in the penstock.

The buckets and fianges'by which they are secured to the core C are castin a single piece. The surface against which the Water strikes is madeconcave, of segments of two circles A A2. The upper portion A', or thatagainst which the water strikes or acts by percussionis a segment of acircle of about six feet diameter, or that part of bucket may be madestraight encircling toward the chute, forming an angle of about seventydegrees. The lower portion A2, or that on which the water reacts, is asegment of a circle of about two feet diameter, and extends from thelower end ot' the upper section. The flanges extend at right angles fromeither side, following the curvature of the bucket, and are perforatedfor the screws which fasten it to the core, being ccuntersunk therein.

Behind each bucket is fastened a block B, of wood, of convex figure,filling the space behind the bucket, which would otherwise be lled bywater, which would counteract the motion and add to the dead-weightofthe wheel and thus impede its progress. The wheel is fixed to avertical shaft' D, which turns in a step and cap in the usual manner.

The penstock F is made so as to admit the wheel to receive the force ofthe water in the most effectual manner. For this purpose its ends areclosed by boards G, arranged at right angles to each other, so as toform a right-angled space in which the tub for the wheel to turn in isplaced, the sides inclosing said space being perforated with obliqueapertures H I to admit the water through corresponding apertures in thetub to the buckets of the Wheel, one of said apertures being made in oneside of the head of the penstock, dac., running parallel thereto, andthe other, which is made in the opposite side, running at right anglesto said lastmentioned aperture. The other end of the penstock is closedin a similar manner, forming a similar space for another tub and wheel,to which ythe water is admitted in like manner, by which arrangementltwo Wheels and four buckets are acted on simultaneously from .the samehead of Water with similar issues, which isysues may be increased innumber or diminished, according to the head of water. A circular rim Kis fastened on the top of the core, and buckets projecting to the outeredges of the latter to prevent the rising of the water above them. Y

Whatlclaim as my invention, and which I desire to secure by LettersPatent, is-

l. The combining with the back of each bucket of the kind set forth aninclined surface, constructed in the manner and for the purposespecified;

2. The mode of combining the wheel with the penstock by constructing thelatter with a recess or cavity into which the wheel is re' ceived, andtwo or more openings for letting on the water, as set forth.
